Al-Madina Souq is the covered souq market located at the heart of the Syrian city of Aleppo within the walled ancient part of the city. Al-Madina Souq is part of the Ancient City of Aleppo, a UNESCO World Heritage Site since 1986.

A souq is a marketplace consisting of multiple small stalls or shops, especially in the Middle East, North Africa, and India. However, temporary open markets elsewhere, such as in the West, might also designate themselves as bazaars. The ones in the Middle East were traditionally located in vaulted or covered streets that had doors on each end and served as a city’s central marketplace. Street markets are the European and North American equivalents.

The city’s strategic trading position attracted settlers of all races and beliefs who wished to take advantage of the commercial roads that met in Aleppo from as far as China and Mesopotamia to the east, Europe to the west, and the Fertile Crescent and Egypt to the south.

With its long and narrow alleys, al-Madina Souq is the largest covered historic market in the world, with an approximate length of 13 kilometers. It is a major trade center for imported luxury goods, such as raw silk from Iran, spices, and dyes from India, and many other products. Al-Madina Souq is also home to local products such as wool, agricultural products, and soap. Most of the souqs date back to the 14th century and are named after various professions and crafts, hence the wool souq, the copper souq, and so on.

Aside from trading, the souq accommodated the traders and their goods in khans (caravanserais) scattered within the souq. Other types of small marketplaces were called caeserias. Caeserias are smaller than khans in size and functioned as workshops for craftsmen. Most of the khans took their names after their function and location in the souq, and are characterized by beautiful façades and entrances with fortified wooden doors.
